列表转换成字典，需要用2个列表转化成字典，一个是key，一个是value。比如：
>>>dict(zip(['a','b','c'], range(5)))
{'a': 0, 'c': 2, 'b': 1}
>>> a=[1,2,3]
>>> ''.join( [ str(x) for x in a])
'123'
>>> b={1:11, 2:22, 3:33}
>>> ''.join( [ str(x) for x in b.values()])
'112233'
>>> ''.join( [ str(x) for x in b])
'123'
>>> ''.join( [ str(x) for x in b.items()])
'(1, 11)(2, 22)(3, 33)'
>>>
a = {'id':1}
b = [1,2]
c = str(a)
d = str(b)
print(c) => "{'id': 1}"
print(d) => "[1,2]"
